| Abstract: | A determiuation of trace so_2 in atmosphcre by conductomltric method is studied in this paper By comparison with cotorimetrie method using pararosanitine itis show that the resuth ohtained from conductometric method is not only as accurate and reliable as the conductometry but also more simple and rapid than colorimetry The study shows That the linearity of the data is satisfy Thc auerage recovery of sample is 95.86%. |
